Advanced, self-balancing video multiplexer system - An advanced video multiplexer system designed and optimized for next generation on-demand video distribution is described. The system optimizes identifies a multi-program transport stream best able to accommodate new sessions based upon Quality of Service (QoS) and QAM utilization ratios. MPTS channels are rebalanced via re-grouping and transrating as necessary to optimize bandwidth utilization. Multiple video formats are supported via built-in transcoding. The multiplexer manages encryption resources and supports new sessions using previously allocated encryption resources where possible. Sessions can be grouped into encryption channels either by using a single authorization tier per channel policy, or by requiring all clients of the group to be in physically separated service groups. Encryption channels can be released when a channel no longer serves any clients or when one or more other channels that have been assigned the same entitlement can accommodate any remaining clients.

TWO-STAGE DIGITAL PROGRAM INSERTION SYSTEM - Apparatus and methods are provided for inserting advertisements and/or to perform grooming functions after a video, audio and/or data stream has been transrated and/or encrypted. In this manner, ad insertion and grooming can be performed close to the edge of a video distribution network. Transrating and encryption of a program into which content is to be later inserted can be accomplished before the program is transmitted. Thus, a single encrypted version of a program can be transmitted from a central point in the network to multiple recipients, while providing the benefits of subsequent targeted ad insertion or grooming downstream of the central point.

MANAGED MULTIPLEXING OF VIDEO IN AN ADAPTIVE BIT RATE ENVIRONMENT - Methods and apparatus for delivering video programs are provided. A plurality of video programs are provided in a fragmented, adaptive bit rate format. A request for a respective video program from the plurality of video programs is received from each of a plurality of clients. The requested video programs are multiplexed for delivery to the clients in a multiplex over a shared, fixed-bit-rate transmission channel. The requests may be for the same or different video programs. The requests for the video programs may occur at the same or at different times. In the fragmented, adaptive bit rate format, the fragment delivered to the client may not be the same as the requested fragment and is dependent on multiple criteria, including the bitrate and quality of the requested and delivered fragments, the total available delivery bandwidth, and other fragment requests made on the channel. The resulting multiplex may be either a constant bit rate multiplex or a variable bit rate multiplex.

Three-dimensionally shaped interpenetrating network hydrogels - Three-dimensionally (3-D) shaped interpenetrating double network (IPN) hydrogel based on a first network and a second network are provided. The 3-D shape is characterized by a non-uniform distribution of the second network (e.g. carboxylic acid groups) when in hydrated state. The 3-D shape can further be characterized by changes in the radius of curvature of the shape. The 3-D IPN hydrogel is created by applying a non-uniform illumination pattern to polymerize the second network of monomers within a layer of a first network. In hydrated state, the second network causes a swelling force that is resisted by the first network. The non-uniformal distribution of the second network with the first network is responsible for the 3-D of the resulting IPN. The invention can find use in ophthalmic applications as well as non-ophthalmic applications.

VIDEO AD SWAPPING IN A VIDEO STREAMING SYSTEM - Configuration of advertisements in a streaming video segment works in cooperation with a client device. Using a selection algorithm, a server selects a first number of default video advertisements for a video streaming session, and a second number of alternative video ads greater than the first number. The server provides identifiers for the alternative video advertisements and transmits the identifiers to the client device prior to a corresponding ad break in the streaming video. During or before streaming of one of the default video advertisements to the client device, the server detects a signal from the client device requesting that one of the alternative video advertisements be swapped for the one of the default video advertisements, interrupts streaming of the default video, and initiates streaming of the one of the alternative video advertisements, in response to detecting the signal. Corresponding operations may be performed by the client device.
